Appliance tip of the week...
Model Number: 110.78942890
Brand: Sears Kenmore
Age: More than 10 years
My gas dryer only has high heat. A month ago it had no heat and I had it repaired, replaced the coils. It worked for about 4 weeks, now low/medium won't work.
Any suggestions on what could be wrong?
Does this happen on auto dry or timed dry? or both?
As a test, pull your dryer out from the wall, then take the exhaust hose off the dryer completely, then run a test load and see if you get the same results or not.
If its still doing it, then its possibly your thermistor or control board.
First you'll need a multimeter (http://www.repairclinic.com/referral.asp?R=153&N=964740) to ohm test the thermistor, unplug the dryer first and remove the 2 wires from it, then it should read 10K ohms (10,000) ohms at room temperature.
The thermistor, Its #42 here (http://c.searspartsdirect.com/lis_png/PLDM/P0203276-00003.png).
It mounts on the blower wheel housing, and sits next to the white thermal fuse.
Remove the two #3 screws to take off the #45 lint duct assembly to get good access to it.
Here's the thermistor for your model you can order here if needed: Manufacturer part# 8577274 (http://www.repairclinic.com/referral.asp?R=153&N=1181075).
The lower access panel unclips as you can see here, two clips on each side, I use a putty knife and push-in on the two clips here (http://www.applianceaid.com/newimages/ldrwp4r-panel-off2.jpg).
Let us know how the repair goes.
